Hot rolled stainless steel plate sheet refers to a stainless steel plate produced by hot rolling. Hot rolling is a manufacturing process in which a metal ingot or billet is heated to a high temperature and passed through a series of rolls to reduce its thickness and shape.
Key Steps For Hot Rolled Stainless Plate Sheet:
1. Heating: Heating stainless steel ingots or billets to a temperature above their recrystallization point, usually at 1000°C or higher. This high temperature makes the material deform and shape more easily.
2. Rolling: The heated stainless steel is then passed through a series of rollers that gradually reduce its thickness. These rollers apply pressure to the material, making it elongate and thin. The process also helps improve the surface finish and mechanical properties of stainless steel.
3. Cooling: After hot rolling, the stainless steel plate is usually cooled to room temperature in the air or by water or other cooling methods. The cooling rate affects the final properties of the sheet.
Key Advantages of Hot Rolled Stainless Steel Plates
| Feature | Advantage to Procurement & Production |
| Cost-Efficiency | Lower processing costs compared to cold-rolled plates, offering a budget-friendly option for heavy structural use. |
| Thicker Gauge Options | Available in heavy wall and large thicknesses (up to 100mm+), which cold rolling cannot achieve efficiently. |
| High Toughness & Formability | Relieved of internal stress during hot working, making it easier to weld, cut, and form without cracking. |
| Corrosion Resistance | Retains full alloy protection against chemical, marine, and atmospheric corrosion when properly pickled. |
Hot Rolled vs. Cold Rolled Stainless Steel Plate: Key Differences
Choosing between hot rolled and cold rolled stainless steel depends on your project's dimensional and aesthetic requirements:
Surface Finish: Hot rolled plates feature a coarse, scaled matte gray (No. 1) finish, whereas cold rolled plates offer a smooth, bright surface (2B or BA finish).
Dimensional Precision: Cold rolling yields tighter tolerances and sharper edges. Hot rolling allows for slight dimensional variances due to cooling thermal contraction.
Thickness & Scale: Hot rolling is ideal for thick plates (above 3mm to 100mm+), while cold rolling is primarily used for thinner sheets (under 6mm).
